Examining learner-computer interactions: advanced lab-based research methods Jonathan P. San Diego of King's College London presented an approach to examining learner-computer interactions using strategy as a unit of analysis developed within his PhD. He showed some of the data collection and analysis techniques that include capturing attention via eye-tracking, capturing sketches via tablet computers, integrating the analysis of multiple video feeds, and using strategy as a unit of analysis. Jonathan also gave some of his reflections on potential future uses of these research techniques.
